securement to the bowl, and further being provided with brackem for hingedly mounting the annular seat thereon,

mounting pivots for the seat being selectively reversible for adjustably changing the relative for-and-aft position of the annular seat, particularly when changing from one assembly to 4/239 4 the other. An important feature of the annular seat resides in 4/254 the provision of side hand grips between which a hinged cover 4/240 or lid is movable to a closed position.

T -JT I I l l i COMBINATION TOILET SEAT AND ELEVATOR THEREFOR BACKGROUND OF THE INVENTION The present invention relates generally to waste disposal apparatus, and more particularly to an occupant seat structure for toilet bowls.

Toilet bowls as conventionally arranged are provided with a low-level hinged seat or ring which presents a very real and vital personal problem in many instances, particularly in the case of elderly people, and others who encounter inconvenience and painful distress when required to sit at the usual low-level, but find comfort and relief from pain and its attendinguncomfortable circumstances, when sitting at a higher or elevated level. A problem also exists in cases where persons confined to a wheel chair are required to transfer from the chair to the seat of a low-level conventional toilet bowl'arrangement. By utilizing the high level arrangement which is made possible in the'present invention, change of position from the wheel chair to the seat of the toilet bowl, and vice versa, is materially aided. I

Various structures have been suggested heretofore for coping with the above mentioned problem, but in the main these suggested arrangements have only partially been successful, and in most cases have involved structures of a rather complicated nature, and have involved the use of components which were not readily adaptable for use in a low-level arrangement, and which could later by the addition of readily available components be reassembled to provide a highlevel or elevated'seat arrangement, when such need should later arise.

I has been previously known, for example, in US. Letters Pat. No. 3,364,505 to provide a seat which is mounted at the top of a compensating riser or adapter in which an elevating hollow skirt is interposed between the seat and a supporting surface on the toilet bowl. The seat and riser or elevator provide a self-contained applicable and removable bowl attachment for use in lieu of the customary lid-equipped hingedly attached occupant seat. The seat portion of the device of the patent is fixedly positioned and cannot be hingedly raised or lowered, and does not provide the usual lid or cover. That is to say that the device of the patent does notprovide a complete seat or cover arrangement in the raised-level position which is compatible with the usual low-level installation. Moreover, the seat portion of the patent device lacks the side handles of the present invention which provide hand grips for the person while transferring to and from the seat or while seated thereon.

In the present invention, the scat structure embodies a novel annular seat with side hand grips which can be mounted in the usual position of the conventional seat of the conventional bowl or hopper to provide a low-level assembly, and which at a later date is susceptible of being combined with an additional elevator of the prevent invention to provide a raised or high-level assembly. The seat and associated lid or cover operate in a corresponding manner in either type of assembly.

SUMMARY OF THE INVENTION The present invention relates generally to an occupant seat structure for a toilet bowl or a hopper, and is more particularly concerned with a combination of components, certain of which can be initially associated to provide a low-level assembly, and which can later, by the addition of an elevator component, as the need arises, be converted to provide a high level assembly.

A further object of the herein described invention is to provide an improved annular toilet seat with lateral hand grips for the aid and convenience of elderly persons and others in assuming a seated position thereon, arising and otherwise using the toilet bowl.

Another object is to provide a toilet seat of the above character which is readily adapted for attachment to an elevator structure to provide an elevated seatat a height level which will permit invalid persons such as might be confined to a wheel chair to more easily move into the seat and vice versa, and when seated to occupy a position which will not cause the discomfort and other undesirable effects effects which may attend the use of a low-level seat.

Still another object is to provide a seating structure of the character described which permits the use of a hinged lid or cover with the seat, and which makes provision for the operative association and adjustment of the seat and lid to adapt it to either a low-level assembly or a high-level assembly.

It is also an object to provide a composite seat structure which includes an improved elevator component which can be fixedly attached to a toilet bowl, and which at its upper end provides bracket means for the attachment of a hinged seat and hinged associated lid or cover.

A still further object includes the provision of a novel and unique pivot mounting means for hingedly supporting the seat with respect to an upper'waste opening of a toilet bowl or a hopper, and which by simple reversal operation will serve to adjust the seat in a fore-and-aft direction with respect to the waste opening.

Further objects and advantages of the present invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the embodiments of the invention without placing limitations thereon.

DESCRIPTION OF THE SEVERAL EMBODIMENTS Referring more specifically to the drawings, for illustrative purposes the invention in one form is shown as being applied to a conventional toilet bowl or hopper l0 constructed with the usual brim 11 which bounds an upper waste disposal opening 12 and presents an upper flat annular surface 13.

In the embodiment shown in FIG. 1 an annular seat 14 and associated cover or a lid 15 are hingedly supported in a highlevel raised position above the brim 11 by means of an intermediate elevator as generally noted by the numeral 16.

The elevator is formed as a separate component of the assembly and comprises a tubular wall structure which provides an upstanding skirt 17 which is provided intermediate its ends with a peripheral outwardly projecting mounting flange 18 adapted to seat upon the upper surface 13 of the brim. As thus arranged, the skirt is divided into an upper extension portion 19 above the flange l8 and a lower extension portion below the flange l8, and which is adapted to extend into the waste disposal opening 12 below the annular surface 13. The elevator as thus positioned provides an upper continuation of the waste opening 12 at the top of the elevator. At the rear side of the elevator, the mounting flange 18 is provided with spaced apart extensions 21a and 21!), each of these extensions being provided with an elongate end slot 22 (FIG. 3) for receiving thcrethrough a mounting bolt 23 positioned in an opening 24 of a bowl shelf portion 25 at the rear of the bowl, the bolt 23 being secured by an associated nut 26.

The seat 14 is shown as being of single wall construction, and may be fabricated by any suitable method of plastic or other suitable material with reinforcing ribs in a conventional manner. In general configuration the seat is annular or ring shaped and has a wall transverse configuration such as to provide a convex upper surface 27. The inner margin of the seat wall is arranged in the lowered position of the seat to overlap and extend inwardly of the upper edge of the extension portion 19 of the skirt and define a seat opening 28 having communication through the skirt with the waste disposal opening 12 of the bowl.

It is an important feature of the construction of the seat 14 that it is provided with integrally formed side extensions 29a and 29b respectively on its opposite sides. It will be observed that these extensions are outwardly and upwardly inclined and contain openings 30a and 30b so as to provide hand grips 31a and 31b respectively in elevated positions on opposite sides of the seat.

As best shown in FIG. 1, the lid 15 and seat 14 are arranged for hinged movements about a common hinge axes to raised and lowered positions relative to the upper end of the skirt 17. It is desirable to provide spaced bumpers 32 of rubber or other suitable material on the underside of the seat structure for engaging the upper edge of the skirt 17, and in a like manner provide bumpers as indicated by the numeral 33 on the lid for engagement with the upper surface 27 of the seat.

Rearwardly spaced hinge lugs 34-34 are arranged at the rear side of the seat to extend inwardly of similar hinge lugs 3545 formed at the rear side of the lid 15. Each set of seat and lid hinge lugs are supported by pivot means having a construction as will now be described.

As best shown in FIGS. 3 and 4, the pivot means for each set of binge lugs 34 and 35 comprises an elongate member 36 of rodlike material which is formed with a shank composed of a threaded straight portion 37 which is joined with an angularly extending portion 38 with a right angled end portion 39 forming a pivotal support for the associated hinge lugs 34 and 35. The angularly extending shank portion 38 in relation to the longitudinal axis of the end portion 39 is such that the axis of the end portion will be laterally offset with respect to the axis of the straight shank portion 37. The straight portion 37 of each member 36 is secured at the outermost end of a rearwardly extending bracket arm 40 at the upper end of the skirt 17. The straight portion of the shank is positioned in a bore passage 41 and retained by upper and lower nuts 42 and 43 respectively, with underlying washers if desired. It will be observed that as mounted in FIG. 3, the shank portions 38 are inclined in a direction to offset the axis of the end portion 39 so as to place it inwardly of the shank portion 37.

Referring to FIG. 7, it will be readily appreciated that the seat 14 with its side hand grips will provide desirable benefits for certain persons who may be able to utilize a low-level seat arrangement as normally provided for conventional toilet bowls, and that under said circumstances it may not be necessary to provide the high-level arrangement with the elevator as shown in FIG, 3. The seat 14 and associated lid 15 are readily mountable for direct association with the brim ll of the bowl or hopper 10, Due to the difference in the horizontal spacing of the bore passages 41 and the openings 24 in the bowl shelf portion, with respect to the rear side of the waste disposal opening 12, provision is made for appropriately changing the position of the axis of the end portion 39 of the pivot members. For such purpose, the pivot members are interchanged and reversed so that instead of the portions 38 being inclined forwardly, they will be inclined rearwardly, as shown in FIG. 7. In this manner, the seat and lid will be adjusted in a foreand-aft direction so as to appropriately position the seat and lid depending upon whether it is utilized in the low-level arrangement as shown in FIG. 7 or in the high-level arrangement as shown in FIG, 3.

From the foregoing description and drawings, it will be clearly evident that the delineated objects and features of the invention will be accomplished.
